Scorpion - Light primer strikes

openspaces · #1 03-21-2021, 04:21 PM

Looking for suggestions on solving light strikes.

Full factory scorpion with ~8-10k rounds and fully cleaned. Rounds drop freely into chamber and fall out.

Shoots well but starting to get a few rounds that show light strikes. Most will go bang if loaded a second time.

Willing to have a slightly higher trigger pull if it means I’ll have better strikes.

I was going to start throwing some parts at it but figured I’d ask for suggestions here first.

I'd say you might be due for a spring replacement with those kind of numbers. Not sure which spring would be the culprit but it seems like something to consider.

I started getting light strikes with my Black Mamba after only 75K rounds. I replaced the Guide Rod Assembly with a heavier spring from Volquartsen and then helped.

Does the heavier spring help the bolt seat thus giving a little more velocity to the hammer?

Also, just did some revised math on round count. Likely, closer to the 20k rounds. Suffice it to say, it’s due for some maintenance beyond cleaning.

Yes it does and that's what I think helps the ignition.

Have you taken the firing pin out and cleaned crud out and check out spring and flat plunger if not I would do that and scrub it out good with old toothbrush! Just a little advice the cross pin in the volquartsen bolts are tight and need a punch to drive them out

Your round count is about right for the FP rebound spring to break. It's usually just 2 or 3 coils at one end that snap off, so you'd think that wouldn't make much difference. But it does.

I like the Tandemkross 5 pack of springs. Much cheaper than buying them one at a time. And I consider rebound springs and extractors to be high wear parts that need replaced regularly. Typically at 10-15k rounds. I've just started replacing them as a set as preventative maintenance. Failures are exceedingly rare for me now.

I have a full VQ bolt in my home mamba build that I’ll swap into the scorpion to see if that helps. That said I’ve ordered the recoil assembly and FP springs as maintenance items.

The positive in this is I’ve been able to have my 12yo daughter learn how to effectively clear FTF/FTE conditions.

Was it a volquartsen bolt that was giving you light strikes? Or stock ruger bolt

Volquartsen. The gun that is the topic of discussion is a factory build scorpion.

I would call volquartsen they have very good customer service!

Quick low value update

I installed the new FP spring and I have the VQ recoil assembly. I’ll take out to the range in the next couple weeks and see if the FP fixed it and swap in the recoil assembly to see if that makes a difference.

Side note: I did send VQ an email and no response. Couple years ago they would reply within a day. I’ve had a couple inquires and not get a response. I’m not sure what to think of that but it’s also why I’m thankful for the experience on this site.
